Will bone marrow extraction be painful? What is the process?
Mar 01, 2022
The anesthetic is not so painful and can be tolerated; precautions
1 The purpose and method of the examination should be explained to the patient before surgery to obtain cooperation.
2 Strict aseptic operation to prevent infection.
3 items are ready.
4 After the puncture needle reaches the periosteum through the skin, the needle should be perpendicular to the bone surface, and the needle should be rotated slowly to enter the needle. If the bone marrow cavity has been pierced, the needle should be fixed at this time.
5 When taking a bone marrow smear for examination, the negative pressure should be slowly increased. When blood is seen in the syringe, the suction should be stopped immediately to avoid bone marrow dilution. For those who want to do smear and culture at the same time, a few smears of bone marrow should be taken first, and then the bone marrow should be taken for culture. When removing the syringe, insert the needle back quickly to prevent marrow spillage.
6 When puncturing the manubrium, the puncture angle must be parallel to the manubrium to prevent the needle tip from slipping off or piercing the posterior cortex of the manubrium.
care
1 During the operation, pay attention to observe the patient's complexion, pulse, and respiration.
2 When the needle is withdrawn, press the puncture point firmly until no bleeding occurs.
3 The puncture site was observed for hematoma, bleeding and infection signs within 24 hours after operation.
4 Change the dressing at the puncture site once a day.
5 Instruct the patient not to take a bath within three days.
